Title: Detecting circuit of rotational frequency of engine
Inventor: YOKOYAMA TATSUO
IPC: G01R23/06
Filed: 1984-06-15
Abstract: PURPOSE:To prevent an engine from stalling even if deceleration rate is high by increasing the response of an engine rotational speed detecting circuit used for a fuel cutting device at the time of deceleration. CONSTITUTION:A resistor R' is connected in parallel with a discharging resistor R in an integrating circuit 14 to reduce a discharging time constant. Although the resistor R' is connected in parallel with the resistor R when a transistor TR' is turned on, the transistor TR' is turned on when the output of a comparator CMP is turned to H. Said output makes also a condition for turning on a transistor TR, so that a discharging time constant of the circuit 14 is switched from high to low at a timing for switching the set value of the comparator CMP. If the output of the comparator CMP is turned from H to L on the contrary, both the transistors TR, TR' are turned off, so that the set value of the comparator CMP is restored and only the resistor R is used for the circuit 14. Said status means acceleration. Therefore, response at the time of deceleration is improved.

Title: Intra-can surface test method
Inventor: NISHIMURA TERUO
IPC: G01N21/954
Filed: 1978-10-09
Abstract: PURPOSE:To realize a intra-can surface test method which can be applied to the high-speed production line by distributing two rows of the photo diodes with a shift secured between and adjacently and then giving decision to the difference signal of the signal waves of each row obtained by sweeping the intra-can surface. CONSTITUTION:Can 1 is turned once round the can axis along with irradiation of the light given to the intra-can surface via irradiating device 10. While turning of the can, photo diodes A1-A10 and B1-B10 of photo detectors 22 and 23 give a high-speed sweeping to the area of l on the intra-can surface from A1 toward A10 and in the direction of the can axis. The two rows of photo diodes convert the light reception quantity into 10 units of electric signls to then send them to decision device 40. The electric signals sent from detecting device 20 are put into the signals sent from clock pulse generator 42 at device 40. In this case, the two photo diode rows have a shift to each other by the half length of the photo diode in the longer direction, and as a result the waveform signals of different shapes can be obtained. And these difference signals are decided to secure a quick test to the presence or absence of the flaw on the intra-can surface.
